Hank, I need penetrators for 36vdc power to motors (50amp), 12vdc
power to lights (20amp), and other small electronic sensors. Any
thoughts about delron or nylon as a body for machining. Attached
is a design for threaded rod through delron that I came up. The
nuts on the threaded rod probably not necessary if locktite or
epoxy is used on the threads before driving it into the thru-hull
body.<br clear="none">
